Unicode - GCSE Computer Science Definition

Unicode is a universal system that gives every character, symbol, and emoji a unique binary number, allowing them to be used in computers and devices all around the world. It includes letters from different alphabets, like English, Chinese, and Arabic, as well as numbers and special characters. This helps computers show and understand text in many languages without errors. Before Unicode, computers struggled to display all languages correctly, but now it’s easier to send messages and use software no matter where you are or what language you speak. Unicode ensures that all digital text looks consistent and clear on any device.
